SHEET-DELIVERING APPARATUS FOR PRlNTlNG-PRE SSES.

SPECIFICATION forming part of Letters Patent No. 225,666, dated March 16, 1880.

Application filed March 14, 1879.

To all whom it may concern Be it known that I, STEPHEN D. TUCKER, of the city, county, and State of New York, have invented an Improvement in Sheet-Delivering Apparatus for Printing-Machines, of which the following is a specification.

This invention relates to the delivering apparatus of web-printing machines 5 and it consists, principally, in a delivering-cylinder or sheetcarrier provided withmeans for collecting many sheets upon its surface and stripping the same in a single mass or body therefrom, with which is combined a pasting-disk, that runs in such working relation to the periphery of said cylinder or carrier as to apply a longitudinal line of paste to one or more sheets, whereby two or more sheets may be united together.

An apparatus embodying my invention is illustrated in the accompanying drawings, in Which- Figure 1 represents a side elevation; Fig. 2, a plan view Fig. 3, a longitudinal sectional elevation; Fig. 4, an end elevation. Fig. 5 illustrates, in elevation, a view of the means for operating the single-folding blade, said view being taken at the line a a, Fig. 3, and lookin g toward the rear end of the machine. Figs. 6 to 11, inclusive, are diagrams illustrating different positions assumed by the single-folding blade in its operation. Fig. 12 represents a modification of the apparatus in which the primary mechanism is a rotating folding device. Fig. 13 is a longitudinal sectional elevation of the same. Fig. 14 represents a sectional end elevation taken on the line 0 c, Fig. 13, which, like the diagrams Figs. 6 to 11 and Fig. 5, is enlarged to more clearly illustrate the parts.

In order to a ready understanding of the present invention, the primary and secondary sheet-manipulating mechanisms will be successively described and then their conjoint operation explained.

Said primary sheet-manipulating mechanism, chiefly illustrated in Figs. 1 to 4, consists of a revolving cylinder or carrier, 20, provided with mechanisms whereby many sheets will be collected upon its surface, and said collected sheets stripped and delivered therefrom in a single mass or body.

The carrier 20 is shown as a cylinder mounted upon a shaft, 19, which is rotated by gearing connecting it with a moving shaft of a webprinting machine with which this delivering apparatus is adapted to operate.

The tapes 51 52 form conductors leading from the cutting'cylinders of such a printingmachine, and operate to carry the sheets formed thereby to the carrier 20, in like manner as is shown in the United States Patent No. 191,494.

The tapes 51 return over the roller or pulleys 80, and are driven by a roller that is geared to one of the rollers of the tapes 52, that is actuated by the cutting-cylinders of the printing-machine, as is common.

The tapes 52 pass over a portion of the carrier 20, run under the roller 84, and thence pass out over the folding-rollers 34 35 of the secondary sheet-manipulating mechanism, and return over pulleys 36 37 toward the cuttingcylinders.

Between the pulleys S0 and the periphery of carrier 20 are guides 60, that bridge the space between the pulleys and the said carrier, thus forming with the tapes 51 a continuous support for the sheets up to the surface of said carrier, which latter, having a greater surface speed than the cutting-cylinders, accelerates the movement of the sheets and separates them a distance apart to provide a space for the entrance of the points of the switches, as is well understood, and fully described in said Patent 191,494. This carrier is provided with another set of tapes, 53, that are stretched from a roller, 81, driven by a pinion, 83, from the wheel 95, extend partially around the carrier 20, over roller 82, driven by a pinion, 91, from the wheel 95, and return under a roller, 85.

The circumferential portion of the carrier 20, which is unoccupied by the tapes 52 53, is spanned by the depending curved arms of the guides 60, which, with the tapes 52, form the entrance-channel for the sheets and switches 70, which, with the roller 84, form the discharging-channelfbrthesame. Theseswitches also operate to close the latter channel and guide the sheets around with the carrier at proper intervals. Said switches are fast upon a shaft, 10, which is rocked by means of an arm, 8, and a connecting-rod, 59, whose stud or friction-roller enters the groove 87 of the camwheel 97, which wheel has a toothed periphery that gears with the pinion 93 on the carriershaft 19. Asthe pinion 93 makes equal turns with the carrier 20, and is but one-half the diameter of the cam-wheel 97 it follows that the switches will be vibrated in opposite directions at each revolution of the carrier 20, standing with their points entered into grooves in the carrier 20 during one revolution of said carrier, as in Fig. 3, and with said points extended into grooves similarly provided in the roller 84 during the next revolution of the said carrier.

These mechanisms operate as follows: Each sheet delivered onto the carrier 20 from the tapes 51 52 will be nipped upon its surface by the tapes 52 and moved around with said carrier, the switches then standing with their points entered into the grooves in the roller 84 and acting to hold the sheet onto said carrier, so as to direct the same into the nip of the tapes 53, which, with the guards 60, aid its onward movement toward the entrancechannel, when it receives a second sheet upon it. These two sheets now travel together, but, since the switches have mean while been rocked into the position shown in Fig. 3, the leading ends of said sheets will be intercepted by the switches and stripped or guided off through the discharging-channel.

It has been common in applying a longitudinal line of paste to one or more sheets that are to be united as one product to move a pasting-disk alternately into and out of the plane in which the sheet travels, (an example of which moving pasting device is shown in the United States Patent N 0. 195,115,) or to run the printed portions of the web into the plane occupied bya pasting-disk, so as to apply a longitudinal line of paste thereto for a suitable distance, as is shown in said Patent 191,494.

In the present improvement the collectingcarrier 20 is supplied with a pasting mechanism, the pasting-disk 66 of which runs in a paste-vat, 67, and is constantly supported in operative relation with respect to the surface of said carrier by means of the fixed bearings of its shaft and vat. This disk 66 is constantly driven by a pulley, 74, on its shaft, which receives motion through a belt, 78, running over a small pulley, 75, on the shaft of the roller 85. This pasting-disk and its vat are so attached to the framework that they may be readily removed, which removal is effected when it is desired that the sheets shall not be pasted, and also to preserve the condition of the pasting mechanism when not in use.

The carrier 20 is grooved circumferentially at a number of points to admit the points of the switches beneath its periphery, the central groove, 2, of which coincides with the position of the pasting-disk 66, so that when said disk is not in contact with the sheet it will be non-operative, and will not smear the carrier and succeeding sheets.

Bymeans of this arrangement of the mechanism a longitudinal line of paste may be applied to alternate sheets, or to all of anynumber carried in succession around the collectingcylinder, which sheets will thus be united together and to the last one of a pack of such sheets, which, delivered therefrom, pass in a united body off from said carrier through the delivering-channel, for the reason that while the first sheet receives the line of paste, and thus adheres to the second, (if two is the number to be collected,) which two thus united are discharged by the switches, the second sheet does not reach the pasting-disk, which then rotates ineffectively, as just described; but if the carrier 20 collects many sheets (as it may in multiples of two) by driving the cam-wheel 97 at an appropriate speed with respect to that of the carrier, then the first sheet will be pasted, as will the second, third, and every sheet of the complement number passing about its surface except the last, which is discharged before it reaches the pasting-disk, as before described with respect to two sheets, the pasted ones underlying it.

The secondary sheet-manipulating mechanism consists of a rotating folding apparatus arranged to fold the sheets in the direction in which they travel in entering it, or at right angles to the line of their travel. This folding apparatus consists of a single foldingblade supported in a constantly-revolvin g carrier, which blade is caused to make a S6Illi-I0- tation at each revolution of said carrier, said blade being projected into co-operative relation with a single pair of folding-rollers turnin g in fixed bearings at each second revolution of the blade-carrier.

The single rotating folding-blade 5 is fixed upon a shaft, 4, thatis supported in arms hung upon a shaft, 30, which blade co-operates with the folding-rollers 34 35, that are mounted in stationary bearings, and geared together by toothed wheels 14 15, and driven inunison at a proper speed by a pinion, 31, on the shaft of the roller 35, which pinion receives its motion from a wheel,32, on the carrier-shaft 80. This shaft 30, supporting arms of the blade-shaft 4, with or without the counterbalancing-shaft 63, constitutes an open frame-work or revolving carrier for the rotating folding-blade 5, which carrier is caused to run turn for turn with the carrier 20 by means of a miter-wheel, 41, on its shaft, which wheel meshes with a miterwheel, 40, on the shaft 29 of the toothed wheel This latter wheel receives motion fromits driver 93, that is its equal in size, through the intermediate cam-wheel 97.

The pairs or other number of sheets collected upon the carrier 20 and delivered therefrom through the discharging-channel are conveyed out over the folding-rollers 34 35 by means of a set of tapes, 44, that are stretched from aroller, 43, driven by a toothed wheel, 42, from IIO the wheel 83, over pulleys 45, so as to lie parallel with the tapes 52, thus formingwith the tapes 52 a sheet-conducting channel for carrying the said sheets against the stops 46 in proper position to be folded by the blade 5. This foldingblade 5 is rotated by means of the rock-arms 3 7 on one end of its shaft 4, which rock-arms are actuated by means of a stationary cam, 6, and a flying-cam, 1, Fig. 5, the latter being rotated by the pinions 11 13, which pinion 13 is fast on the shaft 30 of the carrier.

This mode of operating a folding-blade is fully set forth in the United States Patent No. 171,196; but as a single-folding blade operating with the foldingrollers 34 35 at each second revolution of its carrier is especially adapted to coact with the collecting and pasting mech anism, its co-operation therewith will now be explained.

At each revolution of its carrier the shaft of the folding-blade 5 is caused to make a semirotation by means of the flying and stationary cams 1 and 6. When a pair of collected sheets are ready to be discharged from the carrier during its second revolution, as in Fig. 3, the folding-blade5 will then stand as in Fig. 14, and be carried inoperatively past the folding'rollers 3435. While the two carriers make their first revolution a pair of collected sheets will be delivered over the folding-rollers 34 35, and the folding-blade 5 will successively assume the positions shown in Figs. 6 and 7, and, being actuated by said cams, will be rotated and projected between said folding-rollers to fold the pair of sheets between them, as in Fig. 8, and during this time the carrier 20 will have received the first sheet of another pair. As the carriers make their next revolution the second sheet of the pair will have been received upon the carrier, and the pair ready to be discharged, as in Fig. 3. While the foldingblade carrier is making its corresponding revolution its folding-blade 5 will successively assume the positions shown in Figs. 9, 10, 11, and 14. During the last revolution of the carrier the foldin g-rollers 34 35 will have folded and delivered the pair of sheets and be free to receive succeeding pairs.

As the carrier of the folding-blade 5 runs turn for turn with the carrier 20, it follows that said folding-blade will be projected into co-operative relation with the folding-rollers 34 35 once for each two revolutions of the carrier 20that is to say, for each time said carrier delivers a pair of sheets out over said folding-rollers. From this it will be seen that the folding blade will be projected but once into the folding-rollers 34 35 for each pair of sheets delivered beneath it by the collectingcarrier 20.

It will be apparent that this mode of operating a single-folding blade will permit its revolving carrier to be so constructed as to support sheets upon its surface and be supplied with means for collecting sheets thereon,

whereby one sheet will be taken onto the sur-.

face of the carrier during that revolution of it when the single-folding blade is inoperative, and receive a second sheet at its second revolution when the folding-blade is inoperative, whereby the two collected sheets will be folded and delivered as one. This is, however, described in my applications filed May 22, 1878, and September 16, 1878, and is not claimed herein.

The primary sheet-manipulating mechanism may be constructed as a folding apparatus, which arrangement is shown in Figs. 12 and 13. As there illustrated the tapes 53 and the pasting device are omitted, as sheets are not to be collected and no pasting is required. This folding apparatus consists of a carrier, 21, supplied with a folder having two blades, 16 17, and sheet-controlling gripers 22. These gripers, the stationary 24, flyingcam 23, and its driving-pinions 26, are constructed and operated as is described in the aforesaid Patent 171,196.

In the mechanism as arranged in Figs. 12 and 13 the tapes 52 pass from the surface of the carrier 21 under a folding-roller, 27, while the tapes 44 run over its companion folding-roller 28, which rollers are geared together by toothed wheels 38 39, and driven from a toothed wheel, 48, on the shaft of the carrier 21, said rollers being so placed as to co-operate with the folder of the carrier 21.

The secondary carrier, its folding-blade 5, and operating mechanisms are constructed and operated as has been hereinbefore described, except that in the present instance said carrier is caused to make double the number of the revolutions of the carrier 21 by means of the wheel 48, that drives the wheel 49, of half its size, through the intermediate wheel 47, which wheel 49 is on the shaft 29, that carries the miter-wheel 40, (on said shaft 29, as is seen in Figs. 2 and 3,) which drives the miter-wheel 41 on the shaft of the carrier of the blade 5. Each sheet directed to this carrier 21 is in succession doubled into the nip of the folding-rollers 27 28, which sheet is delivered to the tapes 52 44 and carried out over the folding-rollers 34 and against the stops 46, when it is folded through the rollers 34 35 at right angles to the first fold by the folding-blade 5 in precisely the manner described with reference to the corresponding mechanisms shown in Figs. 1 to 11.

It will be seen that the primary mechanism folds a sheet at each revolution; but as the secondary mechanism makes two revolutions to each one of the primary, one of said revolutions must be an idle onethat is to say, the folding-blade 5 will pass then inoperatively by the folding-rollers 34 35.

It will be observed that the secondary mechanism folds a sheet at right angles to the line of travel into said mechanism, and that the space between successive sheets delivered from the primary to said secondary mechanism, rendered necessary in order that one The combination, with a revolving sheetcarrier and means for collecting many sheets thereon, of a pasting-disk running in working relation to the periphery of said carrier, whereby two or more sheets may be collected and their contact surfaces united by longitudinal 15 lines of paste, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
